摘要： PURPOSE: To avoid grounding a rotating brush for a long time so as to avoid injury of a lawn by providing a detecting mechanism for the running speed of a running machine body and a detecting mechanism for the level against the ground of a rotary brush, and controlling an alarming means against the condition in which the rotary brush is on a level in contact with the ground. CONSTITUTION: When a machine body 3 is stopped to run and a rotary brush is on a level in contact with the ground, a buzzer 30 is actuated by a control device 31 as a control means. By actuation of the buzzer 30, an operator can operate to start running of the machine body 3, operate to stop driving of the rotary brush, or operate to raise the rotary brush from the ground. When a fixed time elapses after operating the buzzer 30, a first control valve V1 as a rotation control mechanism controlling rotation of the rotary brush is operated so as to stop rotation of the rotary brush. Further, by the control means 31, the rotor is automatically raised up to a level separated from the ground.

摘要： PURPOSE:To provide a controller for a mowing machine capable of performing the cutting of weeds and avoiding a danger such as a fall even if an abnormality in stopping in a state of a ground contact unit displaced upward is caused. CONSTITUTION:This controller for a mowing machine is constituted by installing the first sensor S1 capable of sensing the extent of vertical displacement of a ground contact unit 26 installed in a mower 4 so as to enable the free vertical movement and the second sensor S2 capable of sensing the lifting and lowering positions of the mower 4 relatively to a mobile machine body 1 and practicing the automatic regulation control over the reaping height for keeping the ground height of the mower 4 at the set ground height based on the extent of the vertical displacement sensed with the first sensor S1 so as to discontinue the practice of the automatic regulation control of the reaping height when the mower position sensed by the second sensor S2 exceeds the position of the set height in the controller for the mowing machine equipped with the mower 4, hung and supported on a mobile machine body 1 so as to enable the free driving, lifting and lowering.

摘要： PURPOSE:To avoid the abnormal wear in a sensor and the detection of an abnormal value by the sensor and control the vehicle speed with good accuracy by directly detecting the actual revolving speed of a hydraulic motor with the rotation detecting sensor using a spline formed on a rotor as a gear for detecting the revolving speed. CONSTITUTION:This vehicle speed detecting device is provided with a rotation detecting sensor S detecting the rotation of a rotary shaft 14 and using the opposite portion of the spline 16a of a rotor 16 coupled with the rotary shaft 14 of a fixed displacement type hydraulic motor M as a gear for detecting the revolving speed, a control device controls the operation of the right and left electric motors based on the number of teeth of the spline 16a for unit time (pulse signal), the trunnion shafts of variable displacement hydraulic pumps are rotatively controlled to change swash plate angles, and the vehicle speed is controlled. The hydraulic motors M are driven by the control action of the control device in response to the operation command from a remote control device having a turn operation lever and a shift operation lever, and the right and left crawler type traveling devices are driven to control the direction and vehicle speed.

摘要： PURPOSE:To revise content of control data with a simple operation by storing new control data to a control data storage means as work control data as a work control means receives a control data revision command. CONSTITUTION:When the control data communication mode is set to a maintenance device (microcomputer checker) 4, the device 4 sends a control data revision command to a work device 1. Upon the receipt of the control data revision command, the device 1 sends an OK signal to the device 4 and the device 4 receiving the OK signal sends new control data to the device 1. The device 1 receiving the new control data stores the data to an IC memory 12. When the transmission of the new control data of a predetermined quantity is finished, the device 4 sends an end signal to release the control data communication mode and the device 1 receiving the end signal terminates the revision of the control data. Thus, a troublesome job is eliminated.
